EL11/EH12 – Master Slave Setting
EL11/EH12
Master slave settings error
•
Check the dip switch settings of the master and slave
•
Check that the XY connection is on the board ok and that it is wired correctly
•
Make sure S isn’t connected from the master to the slave
•
If in doubt, temporarily power down one fan coil and reset the powered unit to a single split on SW8/SW5 (both dips OFF). If
the system comes out of error it means the fan coil is fine. Swap the units. Test this fan coil as well. If both fan coils are good
then it is 100% either the dip switch or the wiring at fault
